Safety Information
General Instructions
To ensure safe operation, the device should only be operated according to the
specifications in the instruction manual. The requisite Health & Safety regulations for a
given application must also be observed. This statement also applies to the use of
accessories.
Every person who is commissioned with the initiation or operation of this device must have
read and understood the operating instructions and in particular the safety instructions!
The work safety instructions in this manual as well as the safety, accident prevention and
environmental protection regulations generally valid for the work area must be observed.
The liability of the manufacturer expires in the event of damage due to improper use, non-
observance of this operating manual, use of insufficiently qualified personnel and
unauthorized modification of the device.
Proper Usage
The nutating disc flow meters D D01 are designed to monitor continuous flow rates of
liquids or gases which do not attack the device materials. All other usage is regarded as
being improper and outside the scope of the device.
In particular, applications in which shock loads occur (for example, pulsed operation)
should be discussed and checked in advance with our technical staff.
The series D D01 flow meter devices should not be deployed as the sole agents to
prevent dangerous conditions occurring in plant or machinery. Machinery and plant need
to be designed in such a manner that faulty conditions and malfunctions do not arise that
could pose a safety risk for operators.
Dangerous substances
For dangerous media such as e.g. Oxygen, Acetylene, flammable or toxic substances as
well as refrigeration systems, compressors, etc. must comply with the relevant regulations
beyond the general rules.
D D01 Instruction manual 03/2023 page 2

Qualifie Personnel
The D D01 devices may only be installed by trained, qualified personnel who are able to
mount the devices correctly. Qualified personnel are persons, who are familiar with
assembling, installation, placing in service and operating these devices and who are
suitably trained and qualified.
Inwar Monitoring
Please check directly after delivery the device for any transport damages and deficiencies.
Additional with reference to the accompanying delivery note the number of parts must be
checked.
Claims for replacement or goods which relate to transport damage can only be considered
valid if the delivery company is notified without delay.
Installation
Before the first installation:
Please flush the meter with fresh water or the medium to measure before the first
installation.
Before installing a meter in a new or modified pipework, the complete pipe system should
be cleaned to remove any impurity like solder, sealing material, welding beads, etc. Inlet
and outlet straight pipe runs are not necessary.
All mounting positions are possible.
Install the meter in such a way that no stress nor strain does effect the meter housing in
order to avoid any damage of threads and/or meter housing. Make sure that the arrow on
the meter housing shows in flow direction.
In case a solenoid valve is used in connection with very frequent switching cycles, the
valve should be mounted on the inlet side of the meter in order to avoid pressure shocks.
To maintain fullpipe conditions, a non-return valve may be mounted at the outlet. To
ensure an exact measurement, please make sure that the measuring chamber is always
fully filled.
Do not place the device on an unstable place where it could fall.
ever place the device near a radiator.
Keep cables away from potential hazards.
Ground the device before installation.
D D01 Instruction manual 03/2023 page 3

Putting into operation
As with any fine instrument, care must be taken in the installation. Your particular meter
may be of special design and may require special information, however, these tips cover
several points of concern with all models.
Please verify the following prior to installation and operation.
Yes o
— Has the piping system been cleaned and is free
of any dirt and particles?
 
— Has a strainer been installed at the inlet of the
meter? (only for P series)
 
— Is mounting position as per requirement?  
— Is flow direction in accordance with the arrow
marking?
 
— Is operating flow within specifications? (The
maximum specified flow rate is an instrument
maximum design flow rate and is not
recommended for continuous operation. For
optimum performance a continuous flow rate
should not exceed 65% of design maximum)
 
— Is material compatibility verified and confirmed?  
— Is operating pressure within limits?  
— Have measures been taken, in case of low
viscous fluids, that the pressure drop across
the meter does not exceed 1.0 bar?
 
— Is operating temperature within limits?  
— Have measures been taken to avoid pressure
shocks? In case a solenoid valve is used in
connection with very frequent switching cycles,
the valve should be mounted on the inlet of the
meter. To maintain full pipe conditions a non-
return valve may be mounted at the outlet.
 
— Does wiring comply with attached wiring
diagram?
 
— Have you carefully read the operating manual?  
Begin start-up only once you have answere all questions with YES.
When putting into operation, always open the upstream valve slowly to apply with the fluid
pressure of the meter and avoid any pressure shocks.
Please make sure that the following parameters are always observed:
a) Maximum operating pressure is 16 bar for the M-series and 10 bar for the P-series.
b) Maximum operating temperature is 50 °C for plastic meters and 120 °C for
bronze meters with LCP chamber.

Evaluation units general
Features:
Large, six-digit LCD display
Display in litres, pints, quarts or gallons freely programmable
11-digit non-resettable totaliser and 6-digit resettable totaliser
Replaceable battery with long life
Stored calibration factor
9-point linearisation
Scalable pulse output (with output signal code B and option D2)
4-20 mA output (for output signal code B and option D2)
Protection class: IP65
Description:
The electronic evaluation unit (register) consists of a microprocessor board powered by a
lithium battery. It can be programmed in litres, pints, quarts or gallons and adds in litres or
gallons.
A calibration factor and a unit of measure are programmed during a factory test. Unlike
mechanical units, these can be electronically recalibrated in the field if necessary. A 6-digit
LC display with three decimal places shows the exact amount of liquid flowing through the
meter. The register is protected from normal wear and tear by a robust, shockproof
housing.
Operation:
The magnets integrated in oval gear counters send pulses to the register.
The register is in sleep mode until pulses arrive. The pulses are generated by the liquid
flowing through the meter.
The register shows the current flow rate, the subtotal and the total.
The resettable totaliser has a 6-digit display with three digits after the decimal point. If the
measured quantity exceeds 999.999, the display jumps over. Then only 2 digits behind the
decimal point 9999.99 are displayed and so on up to the maximum value of 999999. After
999999 is reached, the totaliser starts again with 0.000. When the reset button is pressed,
the totaliser is reset to zero. The register also has a resettable total counter. To reset this,
the total and reset keys must be pressed simultaneously ("Total" key pressed and held,
"Reset" key pressed). This can be used for several subtotals.
The non-resettable totalisers have 11 digits and count arbitrarily in either gallons or litres.

2. Press and release the TOTAL button to select desired the unit of measure
(theselected unit of measure will flash).
3. When the appropriate unit of measure is selected, press the TOTAL button to
advance to the scale factor programming.
D D01 Instruction manual 03/2023 page 14

Scale factor
The register collects input pulses from the oval gear meter and then determines the
appropriate display output using the scale factor. This scale factor varies depending upon
the viscosity of the liquid being measured, therefore calibrating the meter and register in
the appropriate liquid will affect the scale factor. The scale factor is displayed as 5 digits
(on the top row) next to the unit of measure. The scale factor consists of 1 integer digit
and 4 decimal digits (see figure 5).
1. Press the TOTAL button to select a digit (selected digits flash). After cycling
through all 5 digits of the scale factor, the register will return to the unit of measure
selection.
2. Press RESET to change the selected digit. The scale factor must fall between the
values of 0.5000 and 2.0000. The factory preset is set between those values at
1.0000.
3. When finished adjusting the unit of measure and scale factor, press and hold the
TOTAL button for one second to advance to the Pulse Rate section.
NOTE: Error checking will not allow the user to advance to the next screen.
Changing the meter pulse rate
The meter pulse rate (screen is indicated by the “I” on the top row, on the left side) is the
number of pulses per unit of measure as detected by the register. The pulse rate varies
according to the type of attached meter. The bottom row consists of the 5-digit integer
value of the meter pulse rate, whereas the top row consists of the 2-digit decimal value of
the meter pulse rate.
The meter pulse rate is entered in pulses per liter if the selected unit of measure is liters.
The meter pulse rate is entered in pulses per gallon if the selected unit of measure is
gallons, quarts or pints.
1. Press the TOTAL button to select a digit (selected digits flash). Press RESET to
change the selected digit. The pulse rate can be any value between 00000.01 and
99999.99 on the top row; integer values are displayed on the bottom row. Example:
10.45 would display .45 on the top row and 10 would be displayed on the bottom
row.
2. When finished adjusting the pulse rate, press and hold the TOTAL button for one
second to advance to the “register orientation” section.
NOTE: Error checking will not allow the user to advance to the next screen.

Linearisation
Indicated by 1 – 9 on the left hand side of the display, followed by a hyphen (-), this
screen allows the setting of the linearisation (in total 9 points).
Linearisation point 1 (of 9)
Press the TOTAL button to select a digit (selected digits flash). Press RESET to change
the selected digit. The flow rate will be set in the top row of the meter and is displayed in
the unit you selected at step 9.1 (unit of measure). In the sample shown above this would
be the flow rate 0.4 liter per minute. On the bottom line of the meter you can set in the
correction of the error in %. In the sample below, the error at a flow rate of 0,4 liter per
minute would be -7,82%; to correct this, +7,82% needs to be set in (the plus symbol [+]
will not be shown).
Once the adjustment of the linearisation is completed, press and hold the TOTAL button
for one second to advance to the next linearisation point.
Linearisation point 9 (of 9)
umber 9 at the left hand side of the display shows the 9th linearisation point. The sample
shows a flow rate of 250.0 liter per minute and a deviation of the flow meter of +0,15%. To
correct this error, -0,15% needs to be set as correction.
NOTE:
Minimum 3 linearisation points needs to be programmed.
The flow rates do not have to be programmed from low to high; the software will
sort the flow rates automatically, no matter at which point (1-9) they are programmed.
To exit the programming mode:
On any screen, press and hold both the TOTAL and RESET buttons. The screen will
revert back to the programmed scale factor, and then flash. Following the three flashes,
the register display will be blank.

•“20” for 20 milliseconds
•“40” for 40 milliseconds
•“100” for 100 milliseconds
To advance to the next programming screen, hold the TOTAL button.
Output pulse length screen
About Output Pulse Length: The pulse rate duration should take into account the "Pulse
Rate Out" and maximum meter flow rate, to prevent an output pulse duration greater than
the required time between pulses. The Output Pulse Length should be set to less than the
value of “t.”
Per the equation:
Maximum meter flow rate (in GPM or l/m)
t = ----------------------------------------------------------------- x 1000
60 X output pulse rate
where t = the required pulse rate in milliseconds.
The output pulse rate = the programmed parameter (default = 1.00 PPL/PPG)
The maximum meter flow rate = the maximum flow rate of the meter for the application.
